Information disclosure under specific server settings

Published Sep 13, 2021 · Updated Sep 16, 2024

Information leakage in OpenText NetIQ Access Manager before 4.5.4 or 5.0.1 allows remote attackers to read sensitive information via specially configured server settings. The vendor identifies the locus only as server configuration with specific settings and does not disclose the exact operation or endpoint that leaks data. Exploitation requires network reachability and the qualifying configuration; reported impact is information disclosure without documented integrity or availability effects.
